so if show multichannel,it wont be as good as DTS-HD,TrueHD....?


with Onkyo 875 it show multichannel(same with PCM in Yammy?),so it should be as good as "real" DTS-HD,True HD....?

PS3 don't do bitstream

got this somewhere,understand more now

Bitstream

Bitstream: A specific way of transmitting information from one place to another. The Bitstream ‘style’ of data transmission sends “compressed” information (data that has been previously ‘packaged’, or squashed down to save space) to an audio receiver. That receiver must then de-compress (or “decode”) the data before it can be ‘read’ and played by the receiver as sound.

PCM


PCM: “Pulse Code Modulation”. A specific way of transmitting digital sound information from one place to another. The PCM ‘style’ of data transmission sends the info “uncompressed”. This means that when it is sent from the data source (a Blu-ray disc, CD, etc.) to a piece of audio equipment – it can be instantly ‘read’ and played. Compressed data has been previously ‘packaged’, or squashed down to save space on the disc. Compressed data must be Decompressed (or “decoded”) in order to be ‘read’ – like boxing up your book collection when you move, you must unpack your books before you can read them again. PCM is different. Since the data has not been ‘boxed up’, it does not have to be ‘unboxed’ (or “decoded”) before it is usable

PS3 does bitstream. But all it will only bitstream the standard DTS and Dolby Digital only. So for DTS-HD MA and Dolby TrueHD sources, PS3 will take the core DTS and Dolby Digital packet inside the track instead.

Myqd, set the Onkyo receiver listening preset to multich for minimal processing (this will only do appropriate crossovers/speaker settings). Unless you want to add more processing, you can set THX Cinema, etc to your liking. But I like to listen just as the director intended, multich fo me.

Good,simple and clear

...another thing,for DTS-HDMA and Dolby True HD sources from BDs,if using optical input to my old Denon 3300,it only show Dolby Digital most of the time,wny not DTS? or it depends on the sources?

Optical can't carry high bitrate audio due to its limited badwidth. If you set the PS3 to bitstream via optical, it will only send the core DTS/Dolby Digital (yes, even Dolby TrueHD can't be sent via optical). Same as my explanation above.

If you set the PS3 to send PCM via optical, all high bitrate audio format (DTS-HD MA, Dolby TueHD and uncompressed PCM tracks) will be downgraded to 2 channels only.

HDMI is the only way for lossless audio tracks (high bitrate). Unless you use a standalone player with internal decoding plus multi-channel analogue outs (like Panasonic DMP-BD50 or Sony BDP-S550).

Haha bro..

I m in de same boat too.. if there is a diff.. then our tin ears prbbly cant tell de diff..

I d say tat sum ttls are better mixed then others even thou of superior formats.. So far I hv one ttl in 7.1 pcm - Forbidden Kingdom n except for de final few moments of de movie.. i really coudlnt tell if it was 7.1 or 5.1..

Just my 2 cts
Dirtrun

PS3 don't do bitstream...HD audio

Still pening...
Between BD30 and SR875, who'd do better job on decoding? My guess is SR875, but again....

Will need to try all the mentioned settings above.

I suppose my ear is still not yet HD!!! But I do notice on my 875 display it show all the spk like L,R,CENTRE,SURL,SURR & LFE ( SUB WOOFER ) but the SBL & SBR not light up which seem to meant the source is a 5.1 even when I am watching BD. I thought all BD is in 7.1??? Anyone got AV showing all the 7.1 when watching bd?

BTW tq for all the expert answer! Have a very nice day!

Yup,

Lites should all cum on when its 7.1 odo.. Erm for marantz they hv only lites for a single surr back but its still 7 channel disc odo.. for 5.1 only 5.1 lites cum on la

No not all bds are 7.1 .. go to hidef digest n look for de rvws.. they hv de best rvws on most released movies..

I only hv one 7.1 at de moment - Forbidden Kingdom..

Sound mixing/editing is one thing. If you're watching the same movie, nothing's different in that term. So if the movie got all different tracks, then it will sound different for each tracks.

The most noticeable difference for lossless audio is detail. By the word "LOSSLESS" alone you can esily understand this. Everything is copied directly from the studio master. As I explaiend to my friend before, let's say there's a scene that shows one piece of glass bouncing 10 times on the floor. With lossless audio track (DTS-HD MA, Dolby TrueHD, PCM), you'll hear each of the 10 "ting" sound exactly as recorded. But when the studio master is compressed for non-lossless audio track (Dolby Digital, DTS, etc), you may NOT hear the 7th, 8th, 9th or 10th "ting" sound even if you crank it to full volume (are you nuts? ).

That's the difference between lossless and non-lossless. So how about the difference between the lossless audio formats itself?

Each audio laboratory have their own standards for sound imaging, positioning, direction, ambience, etc. These are what make the formats different. They will apply their standards to the studio master while retaining the bit by bit details, meaning it will still be lossless. From my own experience, Dolby is usually be a little softer in their presentation, you may need to increase the volume a little bit (though the Dolby TrueHD on some new titles liek Cloverfiled are really poweful). DTS is more like "in-your-face", it's very hard hitting that some people will say more "ooomph". PCM? They are taken directly from the studio mix, so what's you're listening is exactly as the sound mixer/editors/engineers have done in the studio.

That said, in the end, I don't mind the audio formats anymore. All I care now is that they have lossless tracks on it.

OK, OK..

In theory, using the receiver to decode should be slightly better. Having the player to decode internally and send as PCM will have something called jitter effects. Google for it and you'll have even worse pening lalat!

Most of the New Line titles includes a 7.1 track, and most of recent release from Lionsgate also provides 7.1 tracks. Some HK titles like Dragon Tiger Gate also DTS-HD MA 7.1. Paramount's Top Gun was supplied with DTS-HD MA 6.1 and the newly annoucned Hellboy II from Universal will also hae DTS-HD MA 7.1.

ya,most of the time only DD,when connect with optical out from PS3,but not sure the sources is DTS-HDMA So if the track with DTS-HDMA,it will show DTS even with optical input,right?


i found even both DTS and DTS-HDMA,/True-HD at 5.1,the surround effect on later and the seperation is much more better,especially my sub will definately feel more POWER now

before that i also tot all BDs come with 7.1 but actually not,only few BDs come with 7.1

Bro Aiman, Thank you!!

what you're saying above is.....in order to get Dolby TrueHD or DTS-HD MA from PS3, the audio has to be set on PCM on PS3 setting, even if the AVR has the decoding capability, right?

All tis jargon is just tat.. real life joes wont be able to tell if its 7.1, 6.1 or 5.1 in a blind test.. cum to tink of it , I dont tink I ll be able to either..
Blind.. mind you - not wif de lites of de avr tellin you ..

I m on hidef is most .. foremost for de Pics.. odo is just icin to de cake..

dirtrun, marantz 7002 doesnt have the TrueHD/DTS-MA light to tell you if any of these audio track is on or not.

ps3 dont do bitstream la so it does de processin n my 7002 just hv spkr lites on.. but its pcm odo la.. for forbidden kingdom all 6 spkr lites cum on d 7002 n its 7.1 odo on de ps3 display..

let's see what i am missing (if there's any) later this evening...i think i've set my ps3 to bitstream.

i have The Assembly with DTS-MA on it. even with the standard DTS, its already ground-shaking.

same gose to mine
